It wraps the event loop's scheduling methods and uses Python's sys.audit hooks to detect when blocking functions like open(), network calls, or subprocess operations run in async code, then captures the full stack trace to show you exactly where the problem is.\n\nThe tool is designed for production use with minimal overhead (approximately 13 microseconds per task). You register callbacks to handle detected blocking events, can enable or disable monitoring at runtime, and optionally raise exceptions on high-severity violations during development or testing. It works with both standard asyncio and uvloop, and integrates into ASGI frameworks like FastAPI.","worth_installing":"Yes. It solves a real problem (finding blocking calls in asyncio code) with low overhead, no runtime dependencies, and a permissive license. Active maintenance, Production/Stable status, and zero known vulnerabilities. Suitable for both development debugging and production monitoring. Install if you run asyncio or uvloop and want to catch event loop freezes early."},"id":"aiocop","links":{"html":"https://skillfed.io/packages/aiocop","md":"https://skillfed.io/packages/aiocop.md","pypi":"https://pypi.org/project/aiocop/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-20","license_spdx":null,"license_treatment":"permissive","name":"aiocop","python_support":"supports_current","summary":"Non-intrusive monitoring for Python asyncio and uvloop.
